Title: Method of manufacturing footwear
IPC: B29C39/02
Filed: 1969-05-06
Abstract: A footwear upper and sole, e.g. a ski boot, are integrally cast from a cold crosslinking polymer, e.g. a polyester or polyurethane, within a mould defined between an inner core and an outer mould shell. The core may comprise a last, or the foot for which the boot is intended, which may be covered before moulding with a coating, or a sock of leather. Zones of different hardness and/or colour may sequentially be cast in the mould such as the sole followed by the upper, or by tilting the mould the sole and part of the upper may comprise the same zone. The mould may be opened for the positioning therein of a reinforcement between sequential casting operations. The last 9 and the mould shell 11, Fig. 3, for the casting of a ski boot, Fig. 1, may comprise castings from the boot to be moulded in the same material thereas, the shell 11 being surrounded by a rigid shell 11a which is dismountable for opening of the mould. The last is provided with a sock 14, e.g. of leather, and a sole filler 16, e.g. of wood, and base plates 6, of multiple ratch hooks 5 and hasps 7 are located in the mould before casting, for which the mould is provided with one or more pouring gates 12, and vent holes 13. Parts of the ski boot, e.g. the flaps 21 and 22 which carry the hooks 5 and hasps 7, may be moulded from a material of greater flexibility by blanking off the flap zone of the boot leg by a removable core (25), Fig. 6 (not shown), in a first casting operation, and which core (25) is replaced in a second casting operation by a plug 28 comprising cavities 29 and 31 corresponding to the flaps 21 and 22, and provided with a pouring gate 31 and vents 34.

Title: Axial trajectory sensor having gating means controlled by pulse duration measuring for electronic particle study apparatus and method
IPC: G01N15/12
Filed: 1971-10-25
Abstract: A sensor for use with apparatus operating in accordance with the principles of the Coulter electronic particle studying device, for differentiating between pulses produced by particles passing on axial or nearly axial paths through an aperture and pulses produced by particles passing off center. The pulse duration is measured at some fraction of the individual pulse amplitudes and only those which meet the criteria of duration established by the electronic circuitry are permitted to pass for use in pulse height analysis apparatus following the sensor. The other pulses are discarded on the basis of their greater durations. The apparatus of the invention provides structure for deriving a duration-measuring pulse whose duration is that of the particle pulse at its fractional amplitude, converting the signal into one which has an amplitude proportional to duration, and then subjecting the latter signal to the criteria of duration established as amplitude levels to operate gating means automatically for rejecting the longer duration pulses and passing the shorter duration pulses.

Title: Roasting cocoa
IPC: A23N12/08
Filed: 1978-09-26
Abstract: A process for the continuous roasting of cocoa kernel material, for example cocoa kernel paste or cocoa liquid from raw, shelled, pre- dried, broken and crushed cocoa beans comprises applying liquid cocoa paste for roasting continuously in a thin layer onto a surface over which the paste runs and flushing with a gas flowing in counter-current. Heat is generated in the thin layer of paste by friction and the paste is constantly partially lifted out of the layer and returned to the layer, to which hot air is supplied in countercurrent along and through the region of return of the paste, whereby the paste is brought to roasting temperature in a first phase and then kept at roasting temperature in a second phase and the temperature of the paste is lowered in a final phase. The process provides considerable economic advantages in comparison with conventional processes because of an increase in aroma yield and flavour quality, a saving in cocoa paste, prevention of loss of cocoa butter and reduction of the time required to tumble the roasted paste in a conche.

Abstract: Neutron absorbing articles, such as those in plate form suitable for use in a storage rack for spent nuclear fuel and having such properties as to make them useful in such application for long periods of time, are made by an improved one-step curing method in which a mixture of boron carbide particles, powdered phenolic resin and a minor proportion of a liquid medium which boils at a temperature below 200 DEG C., preferably water, is compacted to desired article form and is cured at an elevated temperature, without simultaneous imposition of pressure in compacting or pressing means, so as to cause bonding of the irreversibly cured phenolic polymer resulting to the boron carbide particles and production of the neutron absorber in desired form. In preferred aspects of the invention the proportions of boron carbide particles, resin and water are respectively, 60 to 80, 20 to 40 and 2 to 8, the resin is a phenol formaldehyde two-stage resin containing hexamethylenetetramine in sufficient quantity to provide formaldehyde to cure it, the resin is of a molecular weight in the range of 1,200 to 10,000, e.g., 6,500, the resin and the irreversibly cured polymer resulting are substantially free of halogens, lead, mercury, sulfur, filler, plasticizer and solvent and the boron carbide particles contain no more than 2% of iron and no more than 0.5% of B2O3. The described method is also employable when a proportion of the boron carbide particles, e.g., 1/10 to 9/10, is replaced by a diluent compound, such as silicon carbide, alumina, silica, graphite, amorphous carbon or mixtures thereof.
